TELEPHONIC TRANSMISSION.

SPECIFICATION forming part of Letters Patent No. 766,451, dated August 2, 1904.

Application filed January 22, 1901. Serial No. 44,299. (No model.)

To (all whom it may concern.-

Be it known that I, ISIDOR KITsEu, of the city and county of Philadelphia'State of Pennsylvania, have invented certain new and useful Improvements in Telephonic Transmission, of which the following isaspecification.

My invention relates to an improvement in telephonic transmission. Its object is to increase the efficiency of the line-wire.

Referring to the drawing, which illustrates in diagrammatic view my invention as applied to two telephonic stations connected together through a metallic circuit, A represents the transmitters of said stations; B,the source of current; C, the primary of an inductorium; D, the secondary of said inductorium; I, the telephonic receiver; E, the metallic circuit; F, condensers distributed along the line of said circuit in series; and G represents inductances, such as coils, distributed along the line in multiple arc.

In my experiments I have found that whereas speech if transmitted over certain lines could not be distinctly heard at the other end of the line the insertion of condensers in series and inductances in multiple produced such an' carried on over a period of years on artificial lines, as well as aerial lines, of a distance of over two hundred miles.

It is unnecessary for me to say that my invention is applicable to overland as well as submarine lines and that with the aid of same a large number of receivers may be placed in the circuit without causing the disturbance and distortion of the transmitted waves they now would cause if their number exceeds the limit.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In electric transmission, a transmittingline, one or more condensers placed in series in said line and one or more coils placed in multiple arc to said line.

9.. In combination, two telephonic stations connected together through a metallic circuit, said metallic circuit provided at different points with condensers in series and also provided at different points with electromagnetic devices in multiple arc.

In testimony whereof I hereby sign my name, in the presence of two subscribing witnesses, this 21st day of January, A. D. 1901.

ISIDOR KITSEE.
